Testing quantum computers with the protocol of quantum state matching
Adrian Ortega, Orsolya Kálmán, Tamás Kiss
The presence of noise in quantum computers hinders their effective operation. Even though quantum error correction can theoretically remedy this problem, its practical realization…
Error-free interconversion of nonlocal boxes
András Bodor, Orsolya Kálmán, Mátyás Koniorczyk
Understanding the structure of nonlocal correlations is important in many fields ranging from fundamental questions of physics to device-independent cryptography. We present a prot…
Sensing microwave photons with a Bose-Einstein condensate
Orsolya Kálmán, Peter Domokos
We consider the interaction of a magnetically trapped Bose-Einstein condensate of Rubidium atoms with the stationary microwave radiation field sustained by a coplanar waveguide res…
Quantum state matching of qubits via measurement-induced nonlinear transformations
Orsolya Kálmán, Tamás Kiss
We consider the task of deciding whether an unknown qubit state falls in a prescribed neighborhood of a reference state. We assume that several copies of the unknown state are give…
Measurement-induced chaos and quantum state discrimination in an iterated Tavis-Cummings scheme
Juan Mauricio Torres, József Zsolt Bernád, Gernot Alber +2
A cavity quantum electrodynamical scenario is proposed for implementing a Schrödinger microscope capable of amplifying differences between non orthogonal atomic quantum states. The…
Quantum walk on the line with quantum rings
Orsolya Kálmán, Tamás Kiss, Péter Földi
We propose a scheme to implement the one-dimensional coined quantum walk with electrons transported through a two-dimensional network of spintronic semiconductor quantum rings. The…
